Specification of Letters Patent.

patented Aug. 21, 1906.

:Application filed August 20, 1897. vSerial No. 648,936.

To a/ZZ whom it may concerm,

Be it known thatI, RUFUs L. PATTERSON, a citizen of the United States, residing at Durham, in the county of Du'rhamand State of North Carolina, have invented certain new and useful Improvements in Machines for Packing Tobacco and other Merchandise, of which the following is a specification.

My invention pertains to machinery for packing tobacco and other merchandise. .In its most complete form the machine is adapted to measure the substance to .be packed, to weigh it with great accuracy, toplace it in bags or other holders and compress it therein, to apply a revenue-'stamp to the package, to apply one or more labels, and, if desired, intro uce a package of cigarette-papers, a card, or other token beneath one of the labels, and finally to deliver the finished packages in regular order to\a tray or receptacle.

The present invention is in the nature of an improvement upon that set forth in Letters Patent No. 579,546, granted to me on the 23d day of March, 1897. mechanism may be operated without of necessity using others, and this may be done either by throwing out of action those parts not required or by embodying in the structure only such parts as are needed for the special work in hand.

The accompanying drawings illustrate my improved machine in its complete form and as specially fitted for filling, stamping, and labeling tobacco bags or packages, it being deemed desirable and important to show and kdescribe in one application the entire or complete mechanism for handling the tobacco from the time that it comes from the granulator to the time that the packages are arranged in order for delivery to the packing tables or boXes.

In ap lications, Serial Nos. 82,906 and 82,907, led in the Patent Office on the 19th day of November, 1901, as divisions of this application, and pursuant to requirements of the Patent Oflice, I have shown, described, and claimed in the first the stamping and labeling mechanism and in the second the measuring and weighing mechanism herein shown and described. Said applications have resulted in patents, application Serial No. 82,906 becoming Patent No. 765,147, of July 12, 1904, and application Serial No. 82,907 becoming Patent No. 754,937, of March 15, 1904.

General Outline of Machine.

It will conduce to clearness and facility of understanding to briefly describe the ma- IOO chine as a whole and thereafter to explain its various groups of mechanism in detail, takin them in the orderin which the tobacco or ot er merchandise reaches and is acted upon by each. In the handling of tobacco and, in fact, with many other kindsof merchandise it is found expedient to place the stockof material on an upper floor andthe Vpacking and labeling mechanism on a lower floor, suitable spouts or chutes leading from the bin or stock-hopper to the measuring mechanism. The present machine employs for measuring a wheel or wheels with buckets or compartments of predetermined size and mechanism for moving said wheels so as to employ one or more than one ofthe compartments at each operation, according to the intended size of the package. The extent of movement of the measurin wheel or wheels at each step is determine by varying the point of connection between the pawl-carrying lever through which the necessary rotation is effected and an actuating-lever of uniform throw. From the measuring-wheel the charge is delivered into a' scale-pan, into which is gradually delivered such additional quantity as shall bring the charge to the precise weight required, essentially as in my former patent, dated March 23, 1897, and numbered 579,546, the du pin of the scale-pan being likewise automatical y and positively effected in a manner similar to that of the previous machine. The scale-pan or the several pans, if there be more than one, will deliver into a single hopper, as before, by which each charge'in turn will be directed into a bagshape, carried by a horizontally-rotatable shape-carrier, which periodically rises to permit the application of a bag to one shape, to carry the receding bag up to the delivery end of the lio per, to carry a filled bag to the bag form an presser, and to move another shape to a oint Where a lever or other device is arrange to act ulpon and collapse it prearatory to the ap cation of another ag; In the present mac e the bag-forms are carried by or form parts of an endless chain which travels over a horizontal bed or table, thence downward, backward beneath the table, and finall upward again to the top of the bed or ta le. This chain is advanced step by step with sufficient delay or dwell between steps to afford time for the several o erations noted and also sufficient to permit 1t e tobacco or other substance to become set in shape. Without an ap reciable dwell of the package while in the orm and subject to pressure there is a liability of its risin as soon as the pressure is removed, and there y impairing the symmetry of the package and causing a slight variation in size. In

that portion of travel of the chain during which the forms descend from the table the packages are (or may be) tied by hand or are otherwise closed, after which they are forced out of the forms one after another.

When thestamping or stamping and labeling ap liances are used, the ejector is so arrange as tov deliver the package directly against a vertically-disposed stamp, previously gummed or asted, the package being thrust between rol ers or folders which cause the stamp to be duly bent or folded about the package. After being thus stamped the package is moved along a horizontal track or way, through which it is lowered against aI district or caution label, which is folded about the package by suitable devices, a l

card, cigarette-paper package, or the like bein first a plied so as to be bound by this la el, if esired. The packages are next moved sidewise beneath a paste-roller, then beneath a label-holder, which descends and leaves a label lightly attached to the face of the packa e, and thereafter passes beneath a resser, w 'ch causes perfect contact of the abel throughout its area and insures thor-- Feed-Hoppers.

In practice it is found expedient and, in fact, almost essential to employ a plurality of measuring and weighing devices operating successively or in alternation in order that each may work slowly enough to insure perfeet action, yet there shall be such frequent delivery of charges as shall enable the packing and labelin mechanism to run rapidly, thus securing igh efficiency both as to quantity and as to quality of work. In the present instance I have represented four measuring and weighing mechanisms, each of which advisably receives its supply from an inde endent hopper of special construction an arrangement, which, however, is not here set forth in detail, but is claimed in Patent IOO lIO

IIS

No. 754,937, issued upon application Serial Column 10 rises from a bed or table 61, sup.

ported by the main frame 62 of the machine.

l Shape- Cawfier.

Rising from the bed or table 61 is a hollow ost or column 63, in which is mounted a vertical shaft or spindle 64, capable both of a rising .and falling motion and of rotation about its axis. Mounted upon the upper end of this spindle is a four-armed head 65, the arms being arranged at right angles to one another or ninety degrees apart. Each arm carries a bag-shape 66, having a hin ed side portion 67 at the lower end, designe to be swung inward to permit a bag to be readily slipped upon it, after which, by pressure upon the hinged side above its pivot, it may be' restored to position, and thus caused to stretch and hold the bag thereon. The manner of mounting and operating the spindle and its shape-carrier is illustrated in Figs. 2, 10, and 11. Referring rst to Fig. 10, it will be seen that the spindle is centrally bored at its lower end to receive the stem of an eyeblock 68, which block is connected with a vertically-movable lever 69 by a pin 70, passing through the slotted end of the lever and through the eye-block, as seen in Fig. 2. A pin 71, passing through a hole in spindle 64 and fitting a groove in the stem of eye-block 68, connects said parts, yet permits free rotation of the spindle independently of the block.

Encircling the spindle 64 is a sleeve 72, which extends upward through an opening in the bed or table 61 and is maintained at proper elevation by a series of antifrietionrollers 73, carried by adjustable blocks 74 and extending into a circumferential groove in the upper part of the sleeve, as seen in Fig. 10. The blocks 74 are slotted and are clamped and held at any desired ad'ustment upon the bed or table 61 by tapolts 75. Beneath the table 61 the sleeve 72 is formed or furnished with a disk 7 6, in the periphery of which are formed four notches 77, de-

, signed to vreceive successively a locking-bolt 78, by which the spindle and its shape-carrying head are held accurately in proper position during operation of other parts. Formed with or secured to disk 76 is a second disk 79, having four radial shouldersor faces 80, connected by long curves or inclines, as seen in Fig. 11, thus making a ratchet-disk. Below the ratchet-disk 79 is a pawl-carrier 81, made in the form of a circular plate encircling the lower or d'epending portion of sleeve 72 and provided with an outwardly-extending arm to which is applied a pawl 82, which engages with the teeth or faces 80 of disk 79 successively. The pawl-carrier 81 is oscillated about the axis of spindle 64 by a vibrating lever 83 through the medium of a connectingrod 84, the lever being shown in Fig. 2 actuated by a cam 112.

`The locking-bolt 78 is pressed forward by a spring 85, encircling the bolt, both being contained within a shell or casing 86, which contains also an annular follower 87, which can be set forward as required by a screw 88 to vary the compression and consequent ressure of the spring. The purpose of the ocking-bolt is to arrest the rotation of the shape-carrier and to hold it in the precise position required while one bag is being applied, another is being filled, another is being packed or compressed, and a fourth is being removed. It is of course'necessary to withdraw or to force back the locking-bolt when the sha e-carrier is to be advanced, and to accomp ish this I provide the pawl-carrier 81 with a cam 89 to act against a roller 90, carried by a slide or bar 91, connected with bolt 7 8, as shown in Fig. 10. As the pawl-carrier 81 moves backward to engage a new tooth or shoulder 8O of the ratchet-disk 79 cam 89 forces back the roller 90, and with it the slide 91 and locking-bolt 78, thus releasing disk 76. As the pawl-carrier again moves forward its pawl advances the disk 79, and with it the released disk 76, the cam 89 gradually riding out from in front of roller 90 and leaving the slide 91 and locking-bolt 78 free to advance, and thus enabling the nose of the bolt to enter one ofthe notches 7 7 as soon as said notch comes into osition to receive it.

The entire weight o the shape-carrier is borne by eye-block 68 and lever 69, so that the rollers 73 have only to support the weight of sleeve 72, its disks, and the pawlcarrier 81, which latter is retained in place upon the sleeve by a nut or collar 92. A spline or feather 93 so connects the spindle 64 and sleeve 72 that they are compelled to rotate in unison, though the spindle is free to rise and fall through and independently of the sleeve.

Referring now to Figs. 2 and 6, it will be IOO IIC

seen that a main driving-shaft 35 is carried i 35 is a pinion 99, which meshes with a gear- 4wheel 100, carried by a shaft 101, mounted in boxes or bearings in the main frame 62. At one end shaft 101 carries a bevel-pinion 102, which meshing with a like pinion 103 gives rotation to a shaft 104, through which the stamping and labeling mechanism is operated. At its other end shaft 101 carries a bevel-pinion 105, which meshes with a bevelgear 1,06, carried at the lower end of a shaft 107, the upper end of which carries a bevelpinion 108, which, asseen in Fig, 2, meshes with a bevel-pinion 109 on shaft 29, thereby rotating said shaft and giving motion to the measuring-wheels and pan-emptying devices through the cam and lever mechanism already mentioned. As seen in Fig. 2, shaft 101 also carries a cam 110, which acting beneath a stud or roller 111, projecting from the side of lever 69, serves to raise and lower' said lever, and with it the shape-carrier, the

lever being conveniently fulcrumed on shaftv 35. Also carried by shaft 101 is a cam 112, grooved in the side face to receive the stud or roller 113 of lever 83, which actuates the pawl-carrier 81, by which the shape-carrier is rotated.

As shown in Figs. 1 and 6, there is located at the forward side ofthe machine a seat 114 for an attendant and'directly in front of him a table or tray with raised sides, the tray being designed'to hold bags or pouches. The operator or'attendant sitting upon the-seat 114 slips a bag or=pouch upon the collapsed lower end of the bag-shape 66 in front of him, taking care to push it well up thereon, and as soon as this is done he presses the hinged side 67 at a point above its pivot, thereby spreading the lower end of the shape and stretching the bag or ouch,- which is at the same time straighten thereon. A little practice enables an ordinary factory hand to do this work deftly and accurately. While the bag orl pouch is being applied and the shapecarrier is in its elevated position, the-bag previously applied to the next shape in advance receives its charge through the funnel 59 from one of the scale-pans 42. At the next turn or step of theshape-carrier the charged bag-or pouch is carried over a bag form or receiver 115 and beneath a presserhead 116, (seenin Figs. 1, 3, 5, and 9,1) the carrier then descending to cause the charged bag or pouch to enter the form or receiver.V

Bag-Forms.

` The bag-forms are shown in Figs. 1 to 5, inclusive, and consist each of a rectangular bottomless box 115. A series of these forms is used connected one with another by links` ceases As seen in Fig. 4, each box or form 115 is provided with lugs or ears 119 to receive the pins or rods 120, by which the links 118 are connected with the forms.- If desired, the ends of these pins or rods Inay be allowed to project beyond the end walls of the forms to serve as axles for antifriction-rolls 121. These rolls may be arranged to project slightly below the ends of the forms, so as to travel upon the surface of bed or table 61 though this is not important, their principal purpose being to insure easy engagement with and disengagement from a notched driving wheel or sprocket 1'22, Figs. 2 and 3. The form-chain passes about four wheels or drums, one, 123, located at the edge or end of table 61, another, 124, located about midway between the ends of said table in the opening therein, a third, 125, carried in an adjustable yoke 126 directly below the wheel or drum 125, and the fourth being the sprocket-wheel 122, located directly beneath wheel 123 and at the same horizontal level as wheel or drum 125. The chain thus produces a parallelogram one side of whichv lies along the top of bed or table 61, which forms a support for that stretch of the chain and for its boxes or forms 115. Where the form-chain rises through table 61, which is near its mid-length, a curved guard or shield 127 is arranged to preventthe chain from encountering anything placed or falling upon the table. The chain, with its formboxes, is required to advance step by step, and in doing so to bring one bag-form directly beneath a bag-sha )e 66 of the carrierhead 65 and another in line with an ejector hereinafter described.

To effect the proper advance and positioning of the boxes or forms, sprocket-wheel 122 or its shaft 128 is furnished with a lratchetwheel 129, and there is loosely hung upon the shaft 128 a lever or pawl-carrier 130, provided With a pawl or dog 131, which as the pawl-carrier oscillates about the shaft alternately rides back over, engages, and presses forward against the teeth of the ratchet- At the point IOS IIO

wheel 129. Pawl-carrier 130 is actuated bi a rod 132, provided with a yoke 133, whic encom asses and is guided upon the hub or boss o' a cam 134, which cam acting between and against two studs or rollers 135 and 136 on the yoke imparts longitudinal motion thereto andv to rod 132.4 The outline of the cam is such that during considerable portions of its revolution it holds the yoke and.

rod at rest, these periods being accurately timed to agree with the periods of charging the bags, compressing, and ej ecting the package. Cam 134 is carried by shaft 101.

It is important that the forms come accurately beneath the presser-head 116 and that they be held against lifting up with the shapes or the presser-head. Eachform isl therefore provided with two horizon-tal ribs also as tracks for the rollers 121, as will beseen upon referring te Fig. 5.

Shape- Oo Zlapser.

It has been mentioned that the bag-shapes 66 have a hinged or pivoted wall 67, which may be thrown inward at the lower end to facilitate application of the bag. For the purpose of thus reducing or collapsing the shape I provide a bunter 140, Figs. 2 and 6, pin- 'ointed to a horizontal stem 141, guided in a lock on the bed or table 61 and periodically pressed forward by a lever 142, connected by a link 143. with a second lever 144, fulcrumed in the main frame 62. The lower end of lever 144 stands in the path of an arm 145, carried by rod 132, as seen in Figs. 2 and 9, and is actuated by said arm as pawl-carrier 130 swings forward to carry pawl 131 into engagement with a fresh tooth of ratchetwheel 129 and at a time when the carrierhead 65 and the bag-shapes are lowered and at rest.

Pressing Mechanism.

A charge of tobacco (or other merchandise) having been delivered into a bag carried by one of the bag-shapes 66 and this shape having been carried to a position directly beneath ,the presser-head 116 and lowered into one ofthe forms 1 15, the head is caused to descend into the shape, and thus into the bag encompassing the lower end thereof, giving the necessary pressure to render the package solid and compact and continuing that pressure a suflicient length of time to cause the contents to become set. After the head has descended and applied the pressure vthe shape-carrier is elevated, leaving the bag within the form 115 and the head 116 still pressing upon its contents. A proper period of rest having been afforded'during which the particles arrange themselves and the package acquires a permanent shape the head 116 rises, leaving the bag and its contents in the form 115, which then advances to a point where the closing-string is tied or the pouch is otherwise closed.

The several movements of the shape-carrier are effected by mechanism already described, and the movements of head 116 are produced by mechanism shown in Figs. 2 and 3. As best shown in the latter figure, the rod or stem 146 of the presser-head 116 is carried by a sliding block or cross-head 147, guided in an upright column or standard 148 rising from. the bed or table 61. The cross head or slide 147 is connected by a pitman 149 with the free end of a lever 150, fulcrumed on the shaft 3.5 and periodically raised and lowered by cam-plates 151 and 152, secured to or formed upon one face of the large gear-wheel 100, carried by-shaft 101. The outlines of these cam-plates and their location upon the gear may be so varied as to give an desired range and time of movement an period of rest, In practice they are so formed and arranged as to draw 'down the head 116 just after the bag is lowered into the form,and to hold it down during the subsequent rise of the shape-carrier the filling of a fresh bag or pouch and until it again becomes necessary to rotate or advance the shape-carrier one step. It will be observed-that the lever 150 is furnished with a stud 153, which enters the groove or space between the camlates 15] and A152, and that this stud is llicated directly over the shaft 101, so that as the lever 150 is lowered :the stud 153 comes nearer the axis ofthe shaft, and the movement of the lever, and consequently of presser-head 116, becomes slower and the force or pressure becomes greater, thus giving the peculiar action so important in pressing.

Tag-Guide.

The package having been duly compressed and carried forward by the form-carrier and the string having been tied or the end otherwise closed, the package passes to an ejector. In some factories it is customary to apply to the bag a rinted tag of strong paper or other suitahle material and a package or book of cigarette-papers. These, attached by a string and free to swing about, are liable to catch into or to be caught by the mechanism, and thus to cause injury to the package or injury or stoppage of the machine. To prevent this, there is rovided a guide 154, (seen in Fig. 2,) whic however, is carried into a divisional application and need not be here described in detail.

The Ejector.

It has been stated that the bags or packages after being duly closed are ejected from the form-carriers in the descending stretch or section of the form-chain. The mechanism by which this is done is shown in Fig. 3. The ejector consists simply of a horizontal rod or bar 163, the forward end of which is carried through a guide attached to the. frame 62 and the other end of which is made fast to a block 164, fitting upon and guided by a horizontal bar 165. Block 164 is connected by a link 166 or in any equivalent way with a lever 167, fulcrumed at its lower end in or upon a part of the machine-frame. Lever 167 is in turn connected by a link 168 with a lever 169, fulcrumed at its upper end in main frame 62 and provided with a stud or roller 170, which is acted upon by a cam 171, carried by shaft 101. This may be a covered cam, in which case it will serve to positively withdraw or recede the ejector, as well as to IOC IIO

move it outward, or it may be merely an lent means-Will be provided to recede-or return the ejector. Arms 176, having overhanging-iianges, engage over the ribs 137 of the .form-boxes as' one after another they come opposite the ejector. These larms prevent the form from moving while the ejector isl acting. All the parts thus far'described" are timed to operate in proper order or sequence; but to guard against the form-chain being carried by momentum a greater distanoeat one throw of its actuatingawl than is desirable shaft 128, Figs. 6 andp carries s rocket-wheel; 122, is provided'with ay stop-w eel 1,72, having notches in its periphery co'rrespl nding in number and arrangement wit -the teeth of ratchet-wheel 129. A spring-pressed locking-bolt" 173- is arranged to engage in the notches of wheel 172 .as they are successivel brought into line therewith, and thus to hol Vthe shaft 128 and the sprocket-wheel 122 against movement untili the bolt is4 withdrawn'. This. occurs once in each revolution o shaft: 1 01' or once in each revolution of shaft 104* b reason of a cam wheel or disk 174, carried y shaft 104, acting against a lateral arm- 17,5 of the bolt, advisably furnished with an antifrictionroller, Fig. 6. Directly in front ofthatpart of the form-chain which passes vertically downward at the end of table 61 there i's arranged a seatv 177 for the attendant, b whom the bag-strings are tied if thismode o closure be adopted, as is commonly done in packing tobacco. This seat is seen* in Fig. 13 supported by an arched cross-bar 178, extending from side to side of frame 62. It is omitted from other figures to permit other parts to be more clearly shown. Foot-rests 179 (seen in Figs. 6 and 9) are provided to give a pro er support for the feet of the attendant an to revent interference with or injury by movlng parts of the machine.

Package-Transfewng Mechanism.

shipment. So much of said mechanismv as is f necessary to the transference of the package from the packin mechanism to the tray w1ll now be describe other matters being omitted because carried into a separate and divisional application.

The ejector 163 forces the ackage from the form 115 to or upon a track or way 158, (seen in top lan view in Fig. 12 and 1n end elevation in igs. 13, 14, and 15, Figs. 14 and 15 showing that portion or section of the track 158 which has hinged or yielding bottom plates or flanges to ermit the package to be forced downward t ough the track to a support beneath.) In passing over the 9, which l track or 'way 158 to the yielding supports 21.1I openoam, in which case a spring or'equiva- Ibel', or the like. .package to the track or 1tself carry it along upon a-stud or bowlcarried-by saidlever214.Y

Directly beneath the yielding portion of the track 158, which is preferably spring-sustained, but -may be counterweighted, is a.

block or carrier 215, which receives the package as it is forced d'own and at proper-'time drops withit to the level of supportlng plate or wa 270'and between guides or guards 264. (See igs. 12 and'17.) In being lowered from the one track or way to the other the ackage receives asecond' pa er strip or labe in the resent instance t e so-called cautionabel required on tobacco-packages.

A horizontally-swinging lever 271, swinging about a vertical axis and moved in one direction by a cam 272 and in the opposite direction by a spring or equivalent means, moves the package along the supporting way or plate 270 to a point in line with a third bed or way 273, whichstands at right angles to the plate 270. The bed or way 273 1s provided with raised edges or guides to insure the retention and proper travel ofthe packages, which are advanced by mechanism il ustrated in Figs. 12 17, and 18. As 'shown in these figures, a horizontalbar 274 is suitably sup orted in the main frame of the machine an serves to sustain and guide a slide 275, whichis connected by a link 276 with the upper end of a lever 277, ulcrumed at its lower end in a suitable bracket or support and connected at an intermediate point with a link 278, connected with an elbow-lever 279, acted-u on by a cam 280. The lever 279 is advisably furnished with a roller for the cam to act against to move it in one direction, and a longand highly-elastic spiral spring 281 serves to move the lever and the connected parts in the reverse direction to that in which they are moved by cam 280.

Projecting horizontally from the side of" slide 275 is an arm 282, Fig. 12, which eX- tends nearly or quite across the bed or way 273 and is at proper hei ht to engage and move a bag or package 2clying thereon. It will thus be seen that as the ackages are carried by sweep 271 to the end) of way 264, one after another, the arm 282 will carry them sidewise or at right angles to their previous travel and deliver them from the way IIC 264 to the way-273, over which are located .devices for delivering paste to the ackages,

Delivery Mechanism.

with the way or table 273 there is located a' wheel or drum 326, provided with outwardly- -projecting blades or wings 327, arranged in pairs, the blades of each pair being parallel to each other and to a line radial to the axis of the drum or wheel. The blades are of a length in the direction of the axis of the wheel about equal to the length of the bag or package and project a distance about equal to the width thereof, While the space between them is sufficiently greater than the thickness of the packages to permit the latter to enter and leave the spaces freely. The position of the wheel or carrier is such that the parallel blades or wings 327, which for the time occupy a horizontal position at the side toward the way or table 273, shall be in proper position to receive between them the package pushed from the outer end of said way, the lower blade of the pair forming a continuation of said way, as seen in Fig. 19.

The wheel 326 is furnished with a ratchetwheel 328, having a number of teeth equal to the number of pockets or receiving-spaces between the pairs of blades or wings 327, and a step-by-step rotation is imparted to the ratchet-wheel, and 'consequently to the carrier-wheel, by a pawl or dog 329, carried by an arm or lever 330, loosely hung upon the axle of said drum or upon the bracket-arm 331, by which said axle is supported, as seen in Fig. 21. A to-and-fro motion is imparted to pawl carrier or lever 330 by a rod 332', one end of which is connected with the lower end of elbow-lever 279, through which motion is imparted to slide 275. (See Fig. 19.) The ratchet and pawl are so formed and set that during the forward or outward movement of slide 275, during which the package is carried into the carrier-Wheel, said wheel remains at rest and the pawl simply rides back over the ratchet-wheel to engage a fresh tooth, the carrier-wheel being turned during the rearward movement of slide 275. Carrierwheel 326 advances the ackages by a series of steps over its upper sie and downward to a point directly beneath its axis, a guard 333 being provided for the lower side of the carrier to prevent the packa es from falling out prematurely. Upon reac 'ng the lower side of the carrier-wheel and clearing the guard 333 the packages drop down and rest u on their edges or narrower sides upon a boar or Way 334, provided with guide-Walls 335., be-

tween which the packages are moved lengthwise, one after another, to a point beyond the outer wall 335 and in line with an ejector 336, by which they are shoved facewise into the tray 337.

The longitudinal movement of the packages between the walls 335 is effected by a rod 338, Figs. 20 and 21, carried by an arm 339, clamped by set-screw or equivalent.

means upon rod 316, which actuates elbowlever 315 and through it the rock-shaft 312. By adjusting the rod in its arm 339 or adjusting said arm upon rod 316 the limit of travel of the rod, and consequently the point at which the packages shall be delivered, may be nicely determined. The package having been'delivered by the rod 338 to a point in front of ejector 336, rods 338 and 340 withdraw by reason of the backward movement of rod 316, elbow-lever 315 being at the same time swung backward and connecting-rod 314 drawn down. Rod 314 carries an adjustable sleeve 345, provided with a lateral stud or finger 346, (seen in Figs. 19 and 21,) which stud engages a bent lever 347, causing its lower end to swing outward and'to give longitudinal motion to ejector 336, with which it is connected by a link 348. The return movement of the lever 347 and ejector 336 may be effected by a spring or equivalent means.

Receiving-Tray.

In tobacco-factories it is customary to place the finished packages in trays of given dimensions and capable of containing an ascertained number of packages, and this is still desirable as a matter of convenience in counting and handling, though it is found that by the selection of a suitable paste and the use thereof in small and uniform quantity the necessity heretofore existing of drying the packages is obviated. This, though an incident to the use of the machine, is a matter of very considerable saving in time, labor, and space required.

In Fig. 1 I have shown the referred lform of tray, with mechanism for e ecting the advance of the rows of packages as one row after another is completed. Referring to Fig. 1, the tray 337 will be seen to consist merely of a rectangular bottom-board with raised sides, being essentially the tray in general use. Within the tray is placed a temporary tray or delivery-board 349, having raised sides and preferably a corrugated bottom. The lower end of the deilvery-board 349. rests upon the bottom of the tray 337, at the IIO lowerend of the latter, while the u per end of the delivery-board rests upon t e raised end wall of tray 337; as shown. At the head of the delivery-board 349 is a board or bunter 350, connected by a rod 351 to one end of a lever 352, the other end of which is periodically engaged by a stud 353 on an endless chain 354,' carried about two sprocket-wheels 355 and 356, the lever being retracted by a` spring 357. Sprocket-wheel 356 is carried by a shaft 358, connected by a knuckle or universal joint 359 Vwith shaft 107, as seen in Fig. 1, shaft 358 being omitted from the other figures to avoid obscuring parts beyond. The board or bunter 350 advances at stated intervals and moves sidewise the entire line or row of packages extending across the tray, moving them one bag length or a little more to make room for the next row. This action is repeated until the delivery-board or temporary tra 349 is filled, whereupon the attendant, ma ing use of a rake or scraper 360, (seen in Fig. 1,) draws all the packages from the delivery-board or temporary tray 349 into the tray 337, which is simultaneously drawn lengthwise from beneath the delivery-board. An empty tray 337 is then substituted for the one removed and the work is repeated.

The rake or scraper is separately shown to the right of the tray in Fig. 1 and on smaller scale for want of space. It is of the same length as the tray or a little more and has at the end of the handle or staff a downwardlybent e'nd or hook, which after the blade or head is dropped back of the rear or uppermost row of packages is dropped over and caused to engage with the lower end of the removable or bottom tray, so that in the act of withdrawing said tray from beneath the deliveryboard or temporary tray 349 the rake 360 draws off the packages into the permanent vtray 337.

Shape- Carrier.

By referring to Figs. 1, 2, 8, and 9 it will be seen that the shape carrier or head is formed with four bifurcated arms and that each bagshape, or the funnel top thereof, is formed with lateral ribs or flanges 377 to rest upon the branches of said arms, where they are held by swinging latches or retaining-bars 378, hinged at one end'to the arms and arranged to swing horizontally to and from a position over the ribs or fianges 377. This construction permits ready application and removal of the shapes, which provision is desirable, since by such change and by proper adjustment of the measuring and weighing devices, the forms, and certain other parts the machine may be readily adapted to prepare packages of different sizes.

The shape-carrier is guided in its vertical movements by an upright stem or post 379,

Figs. 8 and 9, each arm of the carrier being perforated to receive said post inturn, essentially as in the former machine.
